Abstract
The utility model relates to a sandwich presss from both sides core reinforced fleece fabrics, it is including outer, intermediate level and inlayer multilayer structure, outer and inlayer is a kind or several kinds among glass fiber loop bonding felt, chopped strand mat, the non -twist coarse gauze, and the intermediate level is one kind in polyester fiber non -woven fabrics, mekralon non -woven fabrics or the glass fibre mat, and the yarn device is spreaded or the short device weak point of cutting is cut by spreading for above -mentioned skin and inner layer structure, and the intermediate level is directly unreeled by unwinding device, superposes skin, intermediate level and inlayer together again, gets into stitch knitting device, through high -speed loop bonding operation, combines into a whole. This product has easy operation, and matter is light, for the cost -effective advantage of customer, the fine mat layer of middle polyester fiber non -woven fabrics, mekralon non -woven fabrics or glass has fine resin water conservancy diversion effect, and the resin soaks soon, the loaded down with trivial details shop layer stage can be saved to special structure, and form -ing technology is stuck with paste to the hand of the former heavy complicacy of substituted.
Description
Technical field:
The utility model relates to fabric and manufactures field, particularly a kind of sandwich sandwich stitch bonded fabrics.
Background technology:
Need repeatedly laying between existing sandwich sandwich stitch bonded fabrics sandwich construction, laying labour intensity is large, and serviceability is not fine, and can not be used in the field very high to material property, production efficiency is low.And the shock resistance of product and hot strength are not high, easy glide between stratiform, Total Product is poor, and overlay film is not fine; The labour intensity of the laying technology in addition between layer structure is high, and cause cost to increase, production efficiency is low.
Utility model content:
The technical problems to be solved in the utility model is that existing sandwich sandwich stitch bonded fabrics shock resistance and hot strength are not high, easy glide between stratiform, and Total Product is poor, and overlay film is not fine; The labour intensity of the laying technology in addition between layer structure is high, cost is caused to increase, production efficiency is low waits deficiency, and provide a kind of short sandwich fabric of cutting, this fabric unit performance is good, and it is excellent with the associativity of resin, have fabulous operability, shock resistance and the hot strength of end article improve greatly, have and are easy to operation, light weight is the cost-effective advantage of client.
For solving the problems of the technologies described above, the utility model adopts so a kind of sandwich sandwich stitch bonded fabrics, it comprises skin, intermediate layer and internal layer sandwich construction, described skin and internal layer are glass fibre stitch-bonded felts, shortly cut felt, one or more in woven roving, intermediate layer is polyester fiber non-woven fabric, one in polypropylene fiber nonwoven cloth or glass fibre belt, above-mentioned skin and endothecium structure to be sprawled or chopped device is short cuts by spreading yarn feeding device, intermediate layer is directly unreeled by unwinding device, again by skin, intermediate layer and inner stacks are added together, enter loop bonding device, by high speed loop bonding operation, be combined into an entirety.
The utility model has the following advantages: this Total Product performance is good, and excellent with the associativity of resin, has fabulous operability, and shock resistance and the hot strength of end article improve greatly; Ectonexine and intermediate layer, through loop bonding device, by high speed loop bonding operation, are combined into an entirety, and be easy to operation, light weight, for client saves cost, and has good designability; Middle polyester fiber non-woven fabric, polypropylene fiber nonwoven cloth or glass fibre belt layer have good resin guide effect, and resin impregnated is fast; Special structure can save the loaded down with trivial details laying stage, can replace the hand pasting forming technology of former heavy complexity.Can be used for RTM technique, lightweight RTM technique, mould pressing process, vacuum perfusion process etc., be widely used in the fields such as auto industry, shipbuilding industry, communications and transportation industry.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model is a kind of sandwich sandwich stitch bonded fabrics, it comprises outer 1, intermediate layer 2 and internal layer 3 sandwich construction, described skin and internal layer are glass fibre stitch-bonded felts, shortly cut felt, one or more in woven roving, intermediate layer is polyester fiber non-woven fabric, one in polypropylene fiber nonwoven cloth or glass fibre belt, above-mentioned skin and endothecium structure to be sprawled or chopped device is short cuts by spreading yarn feeding device, intermediate layer is directly unreeled by unwinding device, again by skin, intermediate layer and inner stacks are added together, enter loop bonding device, by high speed loop bonding operation, be combined into an entirety.
The Total Product performance of above-mentioned sandwich sandwich stitch bonded fabrics is good, and excellent with the associativity of resin, has fabulous operability, and shock resistance and the hot strength of end article improve greatly; Ectonexine and intermediate layer, through loop bonding device, by high speed loop bonding operation, are combined into an entirety, and be easy to operation, light weight, for client saves cost, and has good designability; Middle polyester fiber non-woven fabric, polypropylene fiber nonwoven cloth or glass fibre belt layer have good resin guide effect, and resin impregnated is fast; Special structure can save the loaded down with trivial details laying stage, can replace the hand pasting forming technology of former heavy complexity.Can be used for RTM technique, lightweight RTM technique, mould pressing process, vacuum perfusion process etc., be widely used in the fields such as auto industry, shipbuilding industry, communications and transportation industry.
Above-described embodiment is one of the present invention preferably scheme, not does any pro forma restriction to the present invention, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
